Since then, the number has grown to 750 million active users presently.

Sundar Pichai, senior vice president of the Android, Chrome and Apps teams, briefly touched on the recent release of the Chromebook Pixel laptop, glossing over the specs and adding that there will be more news on the high-end laptop later this year.

Following up a demo of how the upcoming second installation of The Hobbit franchise has been developed on the Chrome-based machine, Linus Upson, vice president of Chrome engineering, introduced new changes focused on speed, simplicity and security.

One of the major improvements in the last year has centered around JavaScript, which Upson touted is now 24 percent better on the desktop version and 57 percent better on mobile (including a 2.4 times speed boost in last four weeks alone).

Upson introduced WebP, essentially an upgrade from JPEG files with 31 percent reduction in file size. He added that the benefits are "compelling" saving on bandwidth and power.

As for video, YouTube will be adding support for VP9 later this year, an upgrade from H.264 files being that it offers a 63 percent reduction in file size at 3.0 Mbits per second versus 8.2Mbits.

Building on existing HTML5 auto-complete tools, Chrome now has a simpler form consisting of three steps: checkout, review (billing and shipping info), and submit.

The Chrome team also introduced a new UI framework, which includes the ability for developers to build their own HTML tags in a single compartment that can be shared across mobile and desktop platforms along with a toolkit that can take advantage of native components.

The unnamed framework isn't available to all developers yet, but it will be on display during I/O this week.

Developers, members of the media, and Google fanboys will also get a closer look at the Chromebook Pixel this week as attendees will all be given their own units during the show.
